道路桥梁施工中预应力的应用及存在的问题

Application of Prestress in Road and Bridge Construction and Existing Problems

近几年来,随着我国社会经济的迅速增长和建筑工艺的不断进步,预应力技术也在道路桥梁的建设中得到了越来越广泛的应用。与传统的路桥施工工艺和技术相比,预应力技术虽然在起步上相对较晚,但具备很多传统路桥施工工艺和技术难以比拟的优势。预应力技术在道路桥梁的建设中,对于增强道路桥梁的承载能力和使用年限等方面,都有着十分重要的意义。

Recent years,with rapid increase of economic development and improvement of building technology,prestress technology has been more and more widely used in road and bridge construction.Compared with traditional road and bridge construction process and technology,although prestress technology started relatively late,it has many advantages much rather than traditional road and bridge construction process and technology.It has very important significance of prestress technology for improving road and bridge bearing ability and service life in construction.
